Mean = $\frac{0 \times 1+1\times 2+2\times 5+3\times 3+4\times 6+5\times 7+6\times 9}{1+2+5+3+6+7+9}$

Mean = $\frac{134}{33}$

Mean = $4.06$

Hence, The Mean of baseball score is 4.06 .

Use the quadratic formula to find the solutions to the quadratic equation below 2x^2-5x+5=0

Serggg [28]

Answer:

x = (5 + i sqrt(15))/4 or x = (5 - i sqrt(15))/4

Step-by-step explanation:

Solve for x:

2 x^2 - 5 x + 5 = 0

Hint: | Using the quadratic formula, solve for x.

x = (5 ± sqrt((-5)^2 - 4×2×5))/(2×2) = (5 ± sqrt(25 - 40))/4 = (5 ± sqrt(-15))/4:

x = (5 + sqrt(-15))/4 or x = (5 - sqrt(-15))/4

Hint: | Express sqrt(-15) in terms of i.

sqrt(-15) = sqrt(-1) sqrt(15) = i sqrt(15):

Answer: x = (5 + i sqrt(15))/4 or x = (5 - i sqrt(15))/4

Sierra says that she can simplify the side of the inequality shown by combining the terms within the parentheses but that she c

stiv31 [10]

Answer:

Yes, Sierra is correct

Step-by-step explanation:

Given

$4(y + 7) > -3 (4 + 5)$

Required

Is she correct

The right parenthesis has 4 + 5.

This can be simplified as: $4 + 5 = 9$

So, we have:

$4(y + 7) > -3 (4 + 5)$

$4(y + 7) > -3 *9$

The left parenthesis has y + 7.

This cannot be simplified because y is a variable and 7 is a number.

<em>Hence, Sierra is correct.</em>
